Seeing Around Corners Using Smartphone-Grade Lidar
Summary
IEEE Spectrum reports that smartphone-grade LiDAR can see around corners by aggregating weak signals across multiple frames, enabling non-line-of-sight sensing with consumer hardware. The study demonstrates a portable ~100-pixel lidar with single-photon detectors that can reconstruct 3D shapes and track motion of hidden objects, highlighting potential applications in autonomous vehicles and robotics while noting current limitations and avenues for improvement.
